Fixed issues that were encountered when browsing for items on certain devices (such as SIMOTION controllers). Tags with the default data type can now be added and the data type will be determined on its first read.

Added the ability to use the Max Items per Read setting when using Exception mode.

Improved browsing speed when not using the leaf filter.

5.13.191.0

10/15/2013

Fixed an issue where one tag with a bad address would cause all tags to have bad quality with certain XML-DA servers.

Added support for HTTP Authentication.

Added the item path to the tag address. The new syntax is <ItemPath><Delimiter><ItemName>. Tag import will read the item path; if it's not empty, it will build the tag address as displayed above. Users can specify the item path in Static Tags (which are manually created) in the same way. For a list of allowed item path delimiters, refer to the "Channel Setup" topic located in the help file.

Added the channel and device names to the "The item path <Channel>.<Device>.<ItemPath> is no longer available in the server address space" error message.

Added the item path (if it is not empty) to the "The item name <channel Name>.<Device Name>.<Item Path><delimiter><Item Name> is no longer available in the server address space" error message.

5.12.140.0

6/18/2013

Fixed faulty browsing logic where the driver would continue attempting to browse after an error was encountered. This could result in the driver being stuck in a loop while browsing.

Corrected a failure to import tags from servers that do not return the item name in the GetProperties response.

Fixed a defect where if the target XML-DA server returned OPC quality for an item, the driver would set the tag quality to Good during a subscription poll refresh.

5.11.250.0

3/5/2013

Initial release of a new driver used to connect to Third Party OPC XML-DA Servers.

What Is a Driver?

KEPServerEX is more than an OPC server—it's a connectivity platform for industrial automation and IoT. Simply download KEPServerEX, and then select from Kepware's library of more than 150 device drivers, client drivers, and advanced plug-ins to fit the communication requirements unique to your industrial control system.

A driver is a software component that enables KEPServerEX to meet the connectivity requirements of a specific device, system, or other data source. The driver handles all proprietary communications to the data source for KEPServerEX; the client interfaces handle all supported OPC, proprietary, and open standards connectivity to applications that monitor or control the devices.

Drivers may be licensed individually or in suites. Additional drivers can be licensed on demand as connectivity needs evolve.
